If a medication is to be adjusted based on potassium levels, who should be called?

• A. The pharmacist
• B. The physician
• C. The nursing supervisor
• D. The patient’s family

Answer: (B)

When a medication is to be adjusted based on potassium levels, it is crucial to notify the physician. Physicians are responsible for managing the overall treatment plan and making decisions regarding medication adjustments, especially when those adjustments are based on laboratory values such as potassium levels. High or low potassium can significantly affect cardiac function and other bodily systems, so prompt and appropriate adjustments must be made under the physician's guidance.

While the pharmacist may provide information about the medication's properties and potential adjustments, they typically do not make changes to medication regimens without a physician's order. The nursing supervisor’s role may include oversight and support but does not typically involve direct decision-making on medication adjustments. Additionally, the patient’s family would not be involved in clinical decisions regarding medication management, as this is within the purview of the healthcare team and ultimately the physician. Thus, it is essential to communicate with the physician for any necessary medication adjustments based on potassium levels.
